NANO FE3O4
Triiron tetroxide is an inorganic substance with the chemical formula Fe3O4. It is a magnetic black crystal, also known as magnetic iron oxide. It cannot be regarded as "ferrous ferrite" [Fe (FeO2) 2], nor as a mixture of ferrous oxide (FeO) and iron oxide (Fe2O3), but can be approximately regarded as a compound composed of ferrous oxide and iron oxide (FeO · Fe2O3).
This substance is insoluble in water, alkaline solutions, and organic solvents such as ethanol and ether. Natural ferric oxide is insoluble in acidic solutions and easily oxidizes into iron oxide (Fe2O3) in humid air.

Product Usage
Used for magnetic fluids, with high purity, small particle size, uniform distribution, large specific surface area, clean surface, no residual impurities, low loose density, and easy dispersion.
Scope of application
Nano sized Fe3O4 maintains the particle size of magnetic particles in the nanometer range, and magnetic performance testing shows that magnetic particles have superparamagnetism. Its technical indicators meet and exceed the performance of magnetic nano sized Fe3O4 at home and abroad, providing a foundation for the application of various magnetic fluids in China.
Application of nano iron oxide in magnetic sealing: for instruments, machinery, gas sealing, vacuum sealing, pressure sealing, etc; Dynamic seals have a wide range of applications and can achieve zero leakage. They have the advantages of low sealing fluid consumption, shock resistance, no mechanical wear, small abrasion, low power consumption, no aging, self-lubricating, long service life, wide speed adaptability range, simple structure, low requirements for shaft machining accuracy and smoothness, and reliable sealing.
Packaging and Storage
Solid: cardboard drum, bagged packaging.
Store in a ventilated and dry warehouse. The packaging should be sealed and moisture-proof. Avoid high temperatures and store separately from acidic or alkaline substances.
